Moving Bed Biofilm Reactor (MBBR) technology

Content on this page requires a newer version of Adobe Flash Player.

MBBR technology employs thousands of polyethylene biofilm carriers operating in mixed motion within an aerated wastewater treatment basin. Each individual biocarrier increases productivity through providing protected surface area to support the growth of heterotrophic and autotrophic bacteria within its cells. It is this high-density population of bacteria that achieves high-rate biodegradation within the system, while also offering process reliability and ease of operation.

This technology provides cost-effective treatment with minimal maintenance since MBBR processes self-maintain an optimum level of productive biofilm. Additionally, the biofilm attached to the mobile biocarriers within the system automatically responds to load fluctuations.

Process Benefits

Compact Design

A fraction of the size of conventional systems

Expandable

Capacity can be easily upgraded by simply increasing the fill fraction of biofilm carriers

Single Pass Process

No return activated sludge stream required

Load Responsive

Actively sloughed biofilm automatically responds to load fluctuations

Minimal Maintenance

No F/M ratios or MLSS levels to maintain

MBBR processes are an excellent solution for common wastewater applications including:

Moving Bed Biofilm Reactor systems deliver a flexible, cost-effective, and easy-to-operate means to address current wastewater requirements and the expandability to meet future loads or more stringent discharge requirements within a compact design.
